Abstract

SE PRESENTA UN METODO PARA LA FILTRACION DE UN MATERIAL BASADO EN CELULOSA DESMENUZADO, PARA QUE POR EJEMPLO SE PUEDA FORMAR UNA MEZCLA QUE CONTENGA EL MATERIAL DE CELULOSA DISPERSO EN UN SOLVENTE PARA CELULOSA TAL COMO OXIDO DE AMINA. CON LA OPERACION DE DESMENUZADO SE CREAN TANTO PARTICULAS FINAS DE MATERIAL CELULOSICO ("POLVO DE PASTA") COMO PARTICULAS GRANDES DE MATERIAL DE CELULOSICO. AL MATERIAL CELULOSICO DESMENUZADO SE LE HACE PASAR A TRAVES DE UN SEPARADOR PARA SEPARAR EL POLVO DE PASTA DE LAS PARTICULAS GRANDES DE MATERIAL CELULOSICO Y A CONTINUACION SE SEPARA EL POLVO DE PASTA EN UN PROCESO DE FILTRACION.A METHOD FOR THE FILTRATION OF A CRUSHED CELLULOSE BASED MATERIAL IS PRESENTED, SO THAT FOR EXAMPLE A MIXTURE CAN BE FORMED THAT CONTAINS THE CELLULOSE MATERIAL DISPERSED IN A CELLULOSE SOLVENT SUCH AS AMINE OXIDE. WITH THE CRUSHING OPERATION BOTH FINE PARTICLES OF CELLULOSIC MATERIAL ("POWDER POWDER") ARE CREATED AND LARGE PARTICLES OF CELLULOSIC MATERIAL. THE CRUMPLED CELLULOSIC MATERIAL IS PASSED THROUGH A SEPARATOR TO SEPARATE THE PULP POWDER FROM LARGE PARTICLES OF CELLULOSIC MATERIAL AND THEN THE PULP POWDER IS SEPARATED IN A FILTRATION PROCESS.
